Damping properties of A357 alloys and A357-stainless steel composites fabricated under different conditions
(Universiti Malaysia Perlis (UniMAP), 2010)
The lab scale gravity casting technique was used to produce alloy specimens of
nonsuperheated A357 alloy, superheated A357 alloy and composite specimens of
superheated A357-0.5 and 1.0 wt.% stainless steel composites. ...
Effect of chemical modification of eggshells powder filled low density polyetylene composites
(Universiti Malaysia Perlis, 2010)
Eggshells powder filled low density polyethylene (LDPE/ESP) composites were
studied. The composites were prepared by using Z-blade mixer at 1800C using a rotor
speed of 50 rpm for 6 minutes. Sample of composites were ...
Gold leaching process and recovery from gold scraps using ascorbic acid
(Universiti Malaysia Perlis, 2010)
A new process of gold leaching which involves the use of hydrochloric acid, sulphuric acid and sodium nitrate was studied. A series of screening study was conducted to identify the most suitable of these acids that capable ...
The role of alkaline activator in geopolymerization of low-calcium fly ash based geopolymers
(Universiti Malaysia Perlis, 2010)
Inorganic polymers or simply geopolymers were synthesized in this study by the
alkaline activation of local low-calcium (Class F) fly ash. The alkaline activator liquid used for
the activation process was a mixture of ...
The effect of HAP addition on properties F-75 alloy fabricated via P/M 6 for biomaterial applications
(Universiti Malaysia Perlis, 2010)
A Co-Cr-Mo (ASTM F-75) alloy is generally used because of their mechanical properties, good wear and corrosion resistance as well as biocompatibility. In order to obtain chemical similarity and interfacial bond form between ...

A study on nanostructured of anodised aluminium template Synthesised by the mixture of phosphoric acid and acetic acid
(Universiti Malaysia Perlis, 2010)
The formation of anodic aluminium oxide (AAO) film in anodising process has been studied. The anodising process was done in a mixture of phosphoric acid and acetic acid. The purpose of mixed acid solution as electrolyte ...
Effects of solution treatment temperature on the mechanical properties of commercial recycled aluminium alloy cylinder head (A319)
(Universiti Malaysia Perlis, 2010)
The present work was performed to investigate the effect of different solution treatment
temperature on commercial recycled aluminium alloy cylinder head during artificial ageing
process. All samples were sectioned from ...
Mechanical and thermal properties of chitosan filled recycled polyethylene biocomposites
(Universiti Malaysia Perlis, 2010)
The research was focused to investigate the utilization of chitosan biopolymer on
properties of recycled polyethylene (RPE). The effect of chitosan loading of RPE
biocomposites on mechanical properties, thermal properties, ...
